How would I implement saving or save states?

Well it depends what type of game you're creating. If it's a simple puzzle game with multiple levels, for example, you could just create a text or lua file that says what level the player is on. To save it, update the file; to load it, read or dofile the file. If there is more complexity than that, you could have other variables saved in the file, such as money/gold, items, etc. It would help if you told us what type of game you are trying to implement saving for.

Take note of this, andy.

[andyauff]

Fair enough, but if someone asks for help they shouldn't assume that everyone knows what kind of game they are making. And I also see that in his signature, but it would've been nice if he had specified. It's all good though.

umm ok, if you mean for like saving when someone leaves the game and then 2 days later picks it up again and starts the game, then you are going to want .cfg file which is basically a txt file that saves the players.x and .y and current map that it is on, or if it's on a tilemap then just it's position. If you are wanting to just save position when you like pause or something, then you need a state system, I have a tut for state system if you want, and I know of an example of .cfg files if you want that to, just let me know.

Could you give me a .cfg example


And by states you mean gamestate = "game" right if not could you give me the states tutorial aswell

Thanks

[PSProgramer]

umm yeah like gamestates :) you should be able to make your entire game into one while true do loop oo and the link is down, but basically it jus i/o functyions

Haha it's no problem. I'll see if I can work up an example....

To use the note button I would

pad = Controls.read

if pad:note() then
blah blah blah blah
end

right?

[PSProgramer]

umm I think, also isn't there a pad:hold() ?? what is that for??

[TurtlesPwn]

Use a little bit of common sense and/or googling and take a guess.

[wicked_fable]

It depends on what LuaPlayer you are using right? Or do all LuaPlayers let you use the Home, Note, etc. buttons?

Also, again, what is the best way to make a rolling credits ending? Would it be to just write each line of text with y-coordinates that are off the screen and just do something like "y = y + 2?" And is there anyway to do simple effects like fadeouts from one image to another by coding them or are these not possible?

The hold switch...

[PSProgramer]

lol, sry I didn't think of that I was thinking of buttons them self, my bad sry

[dan369]

I've never used pad:hold() i don't think that any game has used it. Its like the least used controls EVER!!
I just don't think that it would be practical in a game. lol

[PSProgramer]

it's used in some apps, I think

[TurtlesPwn]

Actually it would be quite practical. If the user accidentally bumps the hold switch, you can make the game pause so they don't die.

[wicked_fable]

Wipeout Pure puts the game on pause when you flick the hold switch. I actually like that feature.

How would I save the number produced by the math.random function?

[wicked_fable]

I don't know exactly what you want to do but you could write it to a text file. That would 'save' it.

Its for battles it randomly chooses one enemy out of 10 but during the battle the enemy continuously changes

[TurtlesPwn]

Wow. Wow. Wow.

theRandomNumber = math.random(1,10)

[xXChromeXx]

Wow. Wow. Wow.

theRandomNumber = math.random(1,10)

I have that and this is what happens

[TurtlesPwn]

Obviously you keep changing it. You need to not keep setting it to math.random, that will keep changing it. Set it once and leave it.

I need it to change every battle

[Access_Denied]

xXChromeXx, you're put the line inside your loop. Don't do that. Then, every time the loop repeats, it'll change the number. (Which should be about 60 times per second. Just put it before your loop, and you'll be all good.

How does Lua handle Zip files?

Can it extract or put stuff in them?

[Anti-QuickJay]

I don't think and LuaPlayer supports ZIP files.

I could be wrong so you can google.
